Hmm, no unlock request necessary for me at ATT, purchased my gsm iphone from Apple sim free - Verizon would not accept the phone..
Well obviously no unlock requests if you're buying the SIM-Free UNLOCKED iPhone. But not everybody pays full price for a phone. Therefore if you buy a subsidized iPhone from ATT then it will be locked. If you buy subsidized iPhones from Verizon they are unlocked out of the box. Also, the SIM-Free is the same model as the ones Sprint and Verizon sell so it's already whitelisted.
